Patented Sept. 4, 1945 MOUNTING FOR ELECTRON TUBES Tom L. Yates, Erie, Pa., assignor to Lord Manufacturing Company, Erie, P9... a corporation of Pennsylvania Application February 19, 1944, Serial No. 523,015

3 Claims.

"the invention relates to flexible mountings for isolating electron tubes from vibrations.

The invention provides an electron tube mounting having a plate that is formed for attachment to a panel or other support, and having one or more rings formed for receiving electron tube sockets. Each ring is connected to the plate by vibration-isolating bodies of resilient material such as rubber, and the ring and plate are provided with abutments which are arranged in cooperating pairs the members of which are normally spaced from each other to permit limited relative movements between the plate and ring. The abutments are so formed that they engage each other to limit the movement of the ring when a tube is pressed into or removed from a socket that is borne by the ring.

The invention is illustrated in the accompanying drawing of which Fig. 1 is a plan view of the mounting to enlarged scale; Fig. 2 a transverse sectional view taken on the line II-II of Fig. 1; Figs. 3 and 4 detail sectional views taken on the lines III-III and IVIV, respectively, of Fig. 1; and Fig. 5 a side view of the mounting to reduced scale, the mounting having assembled with it an electron tube positioned in a socket that is connected to the mounting.

The mounting shown in the drawing is for a single electron tube, and for that purpose it comprises a plate I having a pair of lugs that are provided with holes 2 for connecting it to a Panel other pport, and having a single circular opening 3. Within this opening there is an inner plate or ring 4 which is provided with a central circular opening 5 and is formed to hold a tube socket. To such end, ring 4 is provided with an inwardly projecting lug So. for properly positioning a socket which is held. on the ring by a snap ring in the usual manner.

Ring 5 is connected to plate I by plurality of bodies ill of resilient material such as soft rubber which are U-shaped to afiord the requisite sensitivity and softness in directions perpendicular and parallel to plate I and in intermediate positions. Four bodies of rubber ID are shown extending between plate I and ring 4 at equal annular intervals, each being provided with laterally extending flanges which are bonded or otherwise suitably connected to the plate and ring. When the ring is so connected to plate I it is freely movable with relation to the plate.

At opposite sides of its opening 3 plate I is provided with two abutment lugs ll which are struck upwardly from the plate and inwardly of the wall of the opening, as shown in Fig. 2.

4 and extend outwardly beneath lugs II, as also shown in Fig. 2. Disposed at right angles to the 'pairs of cooperating lugs H and I2, plate I is provided with downwardly and inwardly extending lugs l3, and ring 4 with upwardly and outwardly extending lugs I l, as shown in Fig. 4, which lugs are also arranged between the adjacent ends of rubber bodies Ill and cooperate in pairs.

In Fig. 5 the mounting is shown as being equipped with a socket 20 in which an electron tube 2i is mounted. When pulling the tube upwardly to remove it from socket 20, the frictional resistance to such removal causes ring 4 to move upwardly as viewed in Figs. 2 and 5 until lugs l2 engage lugs II which limit the upward move ment of the ring. Similarly, when pressing a tube into the socket ring l moves downwardly as viewed in Figs. 2 and 5 until lugs it engage lugs iii of plate I. By thus limiting the relative move- .ments of ring 4 and plate H the soft rubber mountings Ill and their attachments to plate l and ring flare not broken or otherwise impaired.

What I claim as new is:

1. A mounting for electron tubes, comprising a plate formed for attachment to a support and provided with an opening, a socket-receiving ring movably positioned within said opening, and vibration-isolating bodies of resilient material such as rubber spaced angularly around said opening so adjacent ends of the bodies are circumferentially spaced apart and connecting the ring to the plate, the ring and plate being pro vided with cooperating pairs of normally spaced abutments, the respective pairs being spaced apart angularly around said plate opening between said adjacent ends of said bodies, said pairs of abutments being formed to engage each other to limit movements of the ring with relation to the plate when placing a tube-in and removing it from a socket borne by the ring.

2. A mounting for electron tubes, comprising a plate formed for attachment to a support and provided with an opening, a socket-receiving ring movably positioned within said opening, and arched vibration-isolating bodies of resilient material such as rubber spanning the gap between the ring and plate and connecting them to each other, the ring and plate being provided with cooperating pairs of normally spaced abutments alternately struck laterally from opposite sides of the plate and ring and formed to engage each other to limit movements of the ring with relation to the plate when placing a tube in and removing it from a socket borne by the ring.

3. A mounting for electron tubes, comprising a plate formed for attachment to a support and provided with an opening, a socket-receiving ring movably positioned within said opening, and arched vibration-isolating bodies of resilient material such as rubber spanning the gap between the ring and plate and connecting them to each other. said bodies'being spaced at substantially equal intervals angularly' around said plate opening so adjacent ends of the bodies are circumterentially spaced apart, the ring and plate being provided with two pairs of normally spaced abutments, the respective pairs being spaced apart angularly around said plate opening between said adjacent ends of said bodies, said pairs of abutments being formed to engage each other to limit movements oi. the ring with relation to the plate, one pair being effective to limit such movements when placing a, tube in and the other pair for limiting such movements when removing a tube from a socket borne by the ring.
